Public bug reported:
After upgrading my system to Trusty (from precise) I noticed high CPU
loads in Xorg and render errors (Image attached). This occurred with all
the Nvidia proprietary drivers available through "Restricted Drivers".
This only happens on this machine with an old AGP GeForce Series 6 card
(6600), and not on the newer machines with series 500 and 700 nvidia pci
express cards.
After switching to Nouveau everything was fine for a while, no more CPU
pegging from Xorg or render glitches. Then I bought a new monitor to
replace the old CRT. So I switched from the VGA connector to the DVI-D
connector (which I had never used before). Every once and a while the
machine will fail to boot and hangs on the console. I've attached the
console output when this happens as an image below. Compare the image to
the corresponding output when the system boots normally:
